Set S1 = ON, S2 = OFF, V1 = V2 = 3.6 V and V3 = 0 V under normal condition. Increase V4 from 0 V
gradually. The V4 voltage when I1 = 10 µA is the CO “H” voltage (V
Set S1 = OFF, S2 = ON, V1 = V2 = 4.7, V3 = 0 V, and V5 = 9.4 V under over voltage condition. (V5) / I2
is the CO pin internal resistance (RCO(L)).
Set V1 = V2 = 3.6 V, and V3 = 0 V under normal condition. Increase V1 from (V
0.2 V) immediately (within 10 µs). The time after V1 becomes (V

Set V1 = V2 = 3.6 V, and V3 = 0 V under normal condition. Increase V3 from 0 V to 0.5 V immediately
(within 10 µs). The time after V3 becomes 0.5 V until DO goes “L” is the overcurrent detection delay time

Set V1 = V2 = 0 V, and V3 = 0 V, and increase V3 gradually. The V3 voltage when CO = “L” (V
or higher) is the 0 V charge starting voltage (V
Set V1 = 0 V, V2 = 3.6 V, and V3 = 12 V, and increase V1 gradually. The V1 voltage when CO = “H” (V
+ 0.3 V or higher) is the 0 V charge inhibiting voltage 1 (V
Set V1 = 3.6 V, V2 = 0 V, and V3 = 12 V, and increase V2 gradually. The V2 voltage when CO = “H” (V
+ 0.3 V or higher) is the 0 V charge inhibiting voltage 2 (V
